I was wondering if it's possible to restore some of the deleted applications. For example, let's say I deleted a sprint navigation and email,. Will I have to download the whole thing from the the website, or will I still be able to locate the icons for them and download them from there??
Back up/restore only backs up data. Not Applications. You can check app loader in desktop manager. If the application you want to reinstall is there, check the box to reinstall. If not, yes redownload it from sprint. As for the email you need to tell me more about what you did.
